Buffer overflow – In short, an application written by a programmer has a server that accepts no more than the N number of bytes, but the server protocol can accept more bytes several times. The hacker changes the application code in such a way that the number of available bytes that the protocol can receive will be sent to the server, but since the server is not programmed to accept such a large amount of data, it stops working.
Most often, additional means to detect an attack are not required because it can be noticed without them. Network deceleration or inability to load the necessary site may indicate job function email database that an attack is being made on you, but sometimes it is very difficult to find out that an attack has been made. And in order to avoid such situations, there are several ways to detect Ddos attacks:
Signature – qualitative traffic analysis
Static – quantitative traffic analysis
Hybrid – a combination of the two above
Protection against Ddos attacks
To protect yourself from Ddos attacks, you can use various methods, but it is important to understand that perfect protection does not exist at the moment.
Among these methods can be noted: good transit potential and server performance, traffic analysis, the use of reflection equipment, etc.
